the pads and hangers individually about their pivots until they look inthe desired position. In Figures 3 and 4 the pads may be raised orlowered individually by hand, or once the pads are adjusted on the nosethe lenses may be raised or lowered by pulling or pushing on the bridgeuntil the hanger arms lock in the desired position. This can be morereadily accomp lished when the pads are so designed as to grip the nosetightly as is usual in nose glasses.

Many changes may be made in the construction without departing from. thespirit of my invention. For example the hanger may be held: in thedesired position by friction due to the pressure of the hanger againstone or both of the p adjacent surfaces of the arm. V

Now having described my invention so that it may bereadily understood byone skilled-in the art, I claim:

1. In combination in a spectacle or eyeglass,

a bridge, a pair of'l'enses, means for attaching said lenses to saidbridge; an arm; means for at-j 'tachin Saidarm to sai'd'bridge, the freeend of said arm terminating'in a U shaped portion extending rearwardlyfrom said bridge; a hanger; said hanger mounted pivotally at one endbetween theplates of the U shaped portion; a nose pad;
